n Cov ntaub ntawv niaj hnub niaj hnub, xav tau rau cov cuab yeej txheej txheem kev ua tau zoo thiab kev pabcuam lub neej txuas ntxiv mus. Txhawm rau kom tau raws li kev lag luam thiab kev tsim kho vajtse xav tau rau high {1} {{{{{{2} {{2} {{2} {} Cov yas ua haujlwm tau dhau los ua cov qauv siv hlau uas tau hais tseg.
S355j2wp
S355j2wpyog cov huab cua cov txheej txheem hlau qib hlau tshwj xeeb tau teev nyob hauv European Cov Qauv EN 10025-5.
S: Denotes qauv txheem hlau;
355: sawv cev yam tsawg kawg los lub zog muaj zog ntawm 355 mpa;
J2: Qhia txog kev cuam tshuam lub zog hluav taws xob ntawm 27 J ntawm -20 degree;
W: Qhia tawm atmospheric corrosion tsis kam;
P: Qhia ntau dua phosphorus cov ntsiab lus siab dua los txhim kho corrosion tsis kam.
S3555j2Wp yog kev txhim kho qis qis-} all {3} _ tooj liab), CR (chromium), thiab ni (npib tsib). Cov ntsiab lus no ua cov txheej txheem tiv thaiv oxide rau ntawm cov hlau saum npoo av, ua kom tiv thaiv tau zoo ntxiv ntawm cov hlau sab hauv.
Cov Khoom Siv Neeg Kho Tshuab
S35555j2WP tsis tsuas yog ua rau kev ua kom corrosion tsis kam tab sis kuj tswj hwm cov khoom siv neeg kho kom zoo.
- Yield lub zog (REAS): Ntau dua lossis sib npaug zos rau 355 MPa (rau cov phiaj tsawg dua lossis sib npaug nrog 16 hli tuab);
- Tensile lub zog (RM): 470-630 mpa;
- Elongation (a): ntau dua lossis sib npaug rau 20%;
- Kev Cuam Tshuam Lub Zog (Kv2-20): Ntau dua lossis sib npaug rau 27 J.
Nws cov txiaj ntsig zoo heev thiab ducurility kom muaj kev nyab xeeb thiab txhim khu kev qha cov qauv kev ua tau zoo txawm nyob hauv qhov chaw qis- qhov chaw ib puag ncig.
Huab Cua Kev Koom Tes ntawm S3555j2WP
Cov huab cua kuj ntawm S355j2Wp feem ntau cov qauv ntawm cov khoom siv synergistic ntawm nws cov khoom siv alloy. Nyob rau hauv cov atmospheric muaj cov xwm txheej, cov ntsiab xws li Cu, CR, NI, thiab p ntawm cov hlau deg hnov nrog oxygen thiab noo noo los tsim ib qho yeeb yaj kiab oxide. Cov yeeb yaj kiab no yog tuab thiab ua kom khov kho, muaj txiaj ntsig zoo thaiv cov txheej txheem oxidation ntxiv thiab txo qis corrosion tus nqi.
Phosphorus tsis tsuas yog txhawb nqa qhov tsim ntawm kev tiv thaiv xeb tab sis kuj ua rau nws ruaj khov.
Cheeb Tsam Thov
Lub tsev thiab choj qauv
Hauv kev ua lag luam niaj hnub no, S3555j2WP yog feem ntau siv rau sab nrauv phab ntsa, phab ntsa sib ntaub, cov duab puab toj roob hauv pes, thiab saib platform. Nws qhov sib txawv liab reddish- xim av xeb ntses imparts lub ntuj, rustic ua yeeb yam zoo rau kev teeb tsa. Txoj hauv kev no muaj ob txoj kev pab them nyiaj thiab kev thov zoo nkauj zoo nkauj.
Kev Railway Thiab Tsheb Raug
Owing rau nws cov ator atormeric corrosider Kuj, S355J2WP feem ntau ua haujlwm hauv kev tsim cov tsheb ciav hlau, tsheb thauj khoom, thiab cov thawv thauj khoom, thiab ntim. Qhov no ua tau zoo txuas lub neej thaum txo cov kev saib xyuas.
Nqaum thiab chaw muaj chaw
Nyob rau hauv cov teeb tsa cov yam ntxwv los ntawm cov ntsev ntau pos huab, av noo, lossis kev muaj kuab paug loj, s355j2wp ua rau corrosion tsis kam ua ntawm cov roj carbon tib yam. Nws yog qhov tsim nyog rau cov ntawv thov suav nrog cov raj xa hluav taws xob, tso tsheb hlau luam, thiab txhawb nqa vaj tsev.
Nrog rau kev nce qib ntawm lub tsev loj thiab muaj cov tswv yim txhim kho stirfections nyob rau ntau cov haujlwm suav nrog kev tsim kho, tsheb thauj mus los, thiab lub zog.
